viridis

Default Color Maps from 'matplotlib'

Implementation of the 'viridis' - the default -, 'magma', 'plasma',
'inferno', and 'cividis' color maps for 'R'. 'viridis', 'magma', 'plasma',
and 'inferno' are ported from 'matplotlib' < http://matplotlib.org/>, a
popular plotting library for 'python'. 'cividis', was developed by Jamie R.
Nuñez and Sean M. Colby. These color maps are designed in such a way that
they will analytically be perfectly perceptually-uniform, both in regular
form and also when converted to black-and-white. They are also designed to
be perceived by readers with the most common form of color blindness (all
color maps in this package) and color vision deficiency ('cividis' only).

Matplotlib recently [introduced new color maps]
(http://matplotlib.org/style_changes.html) for their graphs. They are called
viridis, magma, inferno, and plasma. viridis was made the new default
color map of Matplotlib.

These four color maps are designed in such a way that they will analytically be
perfectly perceptually-uniform, both in regular form and also when converted to
black-and-white. They are also designed to be perceived by readers with the most
common form of color blindness.
